1.Description:
The mechanical-hydraulic drilling jar is a jarring and stuck releasing tool. It integrates the up jar and down jar and can release the stuck accident occurring during drilling operation. The drilling jar is an ideal tool for directional well and deep well drilling.
Operating principle
1.Operating principle of up jar
Lifting drilling tool, slip assembly which bear the acting of dish reed elastic force and slip locking force compels latch mechanism of slip clasp slip mandrel. While slip mandrel up run with mandrel to overcome slip locking force and damping action between hydraulic valve assembly and spindle extension, jar
Make drill stem accumulate energy, delay time. When mandrel up run to the state of release constraint, elastic potential energy accumulated in drill stem will convert to upward kinetic energy, generate up jar. If need sequence up jar, you need fed off drilling tool till relock latch mechanism, reduplication above process,
Generate sequence up jar.
2.Operating principle of down jar
The loosen load of down jar lock can be transfer as per in demand .There are a certain ratio between up locking force and down locking force , and the ratio is adjustable. If down jar, fed off drilling tool until pressure reach to down locking force, jar should generate down jar force. If need to repeat jar, lifting drilling tool to anew securing position repeat above process.

Drilling Tool
Luhai drilling motor is a positive displacement motor. High pressure drilling fluid fl ows into the drilling motors, thereby enabling the hydraulic energy to be converted into mechanical energy, at the same time, the rotor drives the shaft and bit to rotate to achieve the purpose of drilling.
Luhai produces LZ73, LZ89, LZ95, LZ102, LZ120, LZ127, LZ146, LZ165, LZ172, LZ185, LZ197, LZ203, LZ216, LZ244, LZ286 and other types of drilling motors. They are for drilling diameter of 88.9-660mm. Luhai also design and develop drilling motors with special sizes, different structural features and operating characteristics in accordance with the user's requirements, thus forming different varieties. At present, in addition to ordinary straight drilling motors, Luhai can also provide the following types of drilling motors
1. Bent drilling motors: The bent angle on the universal shaft can meet different kickoff requirement, there are single-bent and double-bent available.
2.Bent angle adjustable drilling motors: The bent angle of the drilling motors can be adjusted on well surface which enhance the extension of kicking off.
3.Extension drilling motors:On the basis of the ordinary drilling motor, improve motor torque to make the bit drilling quickly by increasing motor stage.
4.Hollow drilling motors: To meet the needs of high fl ow rate solids carrying in drilling, hollow rotors with carbide nozzles of different sizes are adopted, which can increase the input fl ow rate and the horsepower of drill bit..
5.Drilling motors with high kick-off rate: Unique structural design, shorter body, bent point closer to the drill bit, and kick-off rate of up to >1°/m.
6.Saturated saltwater mud-resistant drilling motors:To maintain long time operation of drilling motors in saturated saltwater mud, special rotor coating is adopted to provide better corrosion and wear resistance.
7.High-temperature drilling motors:Â In order to improve the high temperature resistance of the stator rubber of the drilling motors, to meet the drilling requirements in high geothermal gradient region and deep and ultra-deep well drilling requirements, high-temperature resistant rubber is adopted to increase the temperature resistance of motor above 150
8.Sealed driving shaft drilling motors:The ordinary mud lubricated driving shaft is replaced with oil lubricated seal driving shaft, which improves the working conditions of the thrust and radial bearings, thus extending the service life of the drilling motors.
